Rumours have abounded about the popular crime series' return, with everyone trying to guess when it make an appearance on Netflix.

Now its vice president has confirmed there is a season two, but there is no set date for the sequel.

“The story is still ongoing, so you will see new episodes coming sometime this year as this story continues to unfold,” Cindy Holland, VP for original content told USA TODAY . “We don’t know when for sure new episodes will be coming."

It looks like Netflix would rather wait for filmmakers Moira Demos and Laura Ricciardi to be ready, than speculate on launch dates.

"Laura and Moira are (in Manitowoc) shooting regularly and working on what the right story is to tell in the next set, so we’re deferring to them on when it will be ready,” Holland sais. “Very few people inside of Netflix actually know the details of what we’re getting because we’re wanting to keep it really under wraps and it is an ongoing case so we’re trying to be sensitive to that.”

What happened in Making a Murderer?

Making a Murderer tells the real-life story of Manitowoc County's Stephen Avery, who spent 18 years in prison for a rape he did not commit.

He was found innocent after new DNA evidence emerged clearing his name. He sued the state.

Avery was then convicted, with nephew Brendan Dassey, for the murder of Teresa Halbach in 2005. She was last seen on his property and evidence suggested he was behind her disappearance.

Her bones were found in the burn pit behind his home. Dassey confessed to the police, saying his uncle raped Teresa before killing her.

The documentary looked at the possibility of Dassey being coerced into making the statement and the holes in the evidence.
